Something I noticed
When The Prowler is "gearing up" before setting out to kill the college students, the framing and length of the shots of him doing so are very similar to the ones in the fake "Thanksgiving" trailer from "Grindhouse," when the killer dressed as the pilgrim is getting prepared for his murders.
I guess that makes one more horror movie reference atop of the Creepshow music and the Halloween-style narration.
